MECHANICAL SYSTEM TESTS
1. PERFORM MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R positions.
NOTICE:

Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature 50
to 80
C (122 to 176
F).

Do not continuously run this test for longer than 10 seconds.

To ensure safety, do this test in a wide, clear level area which provides good traction.

The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect an Intelligent Tester II to the DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot pressed firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
(7) Quickly read the stall speed at this time.
Stall speed: 2,400
150 rpm
(8) Do the same test in the R position.
Stall speed: 2,400
150 rpm
Evaluation:
ProblemPossible cause
(a) Stall engine speed is low in D and R positions

Engine power output may be insufficient

Stator one–way clutch not operating properly
HINT: If the value is less than the specified value by 600 rpm or
more, the torque converter could be faulty.
(b) Stall engine speed is high in D position

Line pressure is too low

Forward clutch slipping

One–way clutch No.2 not operating properly
(c) Stall engine speed is high in R position

Line pressure is too low

Reverse clutch slipping

1st and reverse brake slipping
(d) Stall engine speed is high in D and R positions
Line pressure is too low

SENSOR ”A” CIRCUIT

SENSOR ”A” CIRCUIT LOW INPUT
DTC P0713 TRANSMISSION FLUID TEMPERATURE
SENSOR ”A” CIRCUIT HIGH INPUT
CIRCUIT DESCRIPTION
The ATF (Automatic Transmission Fluid) temperature sensor converts the fluid temperature into a resistance
value which is input into the ECM.
The ECM applies a voltage to the temperature sensor through ECM terminal THO.
The sensor resistance changes with the transmission fluid temperature. As the temperature becomes high-
er, the sensor resistance decreases.
One terminal of the sensor is grounded so that the sensor resistance decreases and the voltage goes down
as the temperature becomes higher.
The ECM calculates the fluid temperature based on the voltage signal.

MONITOR DESCRIPTION
The automatic transmission fluid (ATF) temperature sensor converts ATF temperature to an electrical resis-
tance value. Based on the resistance, the ECM determines the ATF temperature, and the ECM detects an
opens or shorts in the ATF temperature circuit. If the resistance value of the ATF temperature is less than
79 Ω
*1 or more than 156 kΩ*2, the ECM interprets this as a fault in the ATF sensor or wiring. The ECM will
turn on the MIL and store the DTC.
*1: 150C (302F) or more is indicated regardless of the actual ATF temperature.
*2: –40C (–40F) is indicated regardless of the actual ATF temperature.
HINT:
The ATF temperature can be checked on the Intelligent Tester II display.
